B2B vs B2C aren't two starkly different things - it's a spectrum between them.

Freelancers are a notoriously difficult market to sell to as they perceive every dollar spent as coming out of their wallet.

Compare that to a large enterprise company where the person making the buying decision is going to take home the same salary at the end of the week whatever the decision ends up being.

It's easier to sell to one client for 10000, then it is to sell to 10000 clients for 1.

In my startup we're currently courting a company and if we get the deal we'll have all our costs covered + enough for another engineer + some leftover profit.

I believe they're suggesting - in line with the point about not charging $5-$10 - that you should not build lower value SaaS products for eg freelancers (with the author implying that customer group doesn't have much money to spend). And that you should instead target larger business customers that will pay more.

"Sell to businesses, not individuals. Businesses have deeper pockets than individuals"

B2B means selling to other businesses instead of to individuals.

really?
